Forklift Type Test Site

I. Core Composition of the Site

1. Test Subjects

• Entrusting Party: Technical and testing personnel of the forklift manufacturing enterprise.

• Inspection Party: 2-3 engineers from the Special Equipment Inspection Institute, responsible for recording, supervision and judgment.

• Prototype: A brand-new forklift to be certified (internal combustion/electric/warehouse, etc.).

• Load: Standard counterweight blocks (mass error ±1%), simulating the rated load.

2. Standard Test Site (Necessary)

• Main Test Site: Cement/asphalt hardened ground with flatness ≤5mm/m, length ≥60m and width ≥12m.

• Ramp: 10% (about 5.71°) standard ramp, length ≥18m, with horizontal buffer sections ≥6m at both ends.

• Brake Test Track: Straight road surface ≥120m long, used to measure braking distance and thermal fading.

• Stability Test Area: Tiltable platform (longitudinal/transverse) to test anti-overturning capacity.

• Noise/Emission Area: Semi-anechoic chamber or closed environment to measure external vehicle noise and exhaust gas (for internal combustion forklifts).

3. Professional Instruments and Equipment

• Speed and Distance Measurement: Non-contact speedometer, five-wheel instrument, laser range finder.

• Load Monitoring: Pressure sensor, dynamic strain gauge, weighing instrument.

• Performance Testing: Steering angle detector, brake pedal force gauge, fuel consumption meter, current/voltage recorder.

• Safety Protection: Fire extinguisher, insulating gloves, warning cones, emergency medical kit.

II. Full Process of On-site Test (Core Items)

1. Pre-test Preparation (1-2 hours)

• Document Review: Verify drawings, specifications, certificates of conformity, and certificates of conformity for key components (engine, motor).

• Prototype Status Check: Check appearance, hydraulic leakage, tires, fasteners, and safety devices (limit, alarm).

• Instrument Calibration: Power on, preheat and calibrate all testing instruments to zero.

• Site Clearance: Demarcate a warning zone and clear unrelated personnel and vehicles.

2. Core Test Items (Carried out in sequence, about 1-2 days)

1) Mass and Parameter Determination

2) Stability Test (Most Critical Safety Item)

• Static Stability: Use a longitudinal/transverse tilting platform, slowly tilt to the critical angle under no-load/full-load conditions; wheels shall not leave the ground or overturn.

• Dynamic Stability: J-shaped sharp turns, S-shaped pile winding, and emergency braking to test the anti-side turnover capacity during high-speed steering.

3) Loading and Unloading Performance Test

• Measure the maximum lifting/lowering speed, natural sliding amount of forks, mast tilting speed, and eccentric load performance under full-load/no-load conditions.

• 1.33 Times Rated Load Static Pressure Test: Test the strength of the mast, frame and forks.

4) Driving and Power Performance

• Test the maximum speed, acceleration performance and traction performance.

• Climbing Test: Start, drive at a constant speed and park on a 10% ramp with full load; no sliding is allowed.

5) Braking Performance (Safety Core)

• Service Braking: Emergency braking at 30km/h under no-load/full-load conditions to measure braking distance and deviation.

• Parking Braking: Park with full load on a 15% ramp, and keep stationary with handbrake/foot brake for ≥5 minutes.

• Thermal Fading Test: After continuous braking, the braking efficiency shall not decrease significantly.

6) Steering Performance

7) Environmental Protection and Safety Devices

• Noise: Noise beside the driver's ear and external vehicle noise (≤84dB).

• Emission: Measure CO, HC, NOx and particulate matter for internal combustion forklifts.

• Safety Devices: Verify the effectiveness of overload protection, emergency power off, limit switch, overhead guard and warning light.

8) Reliability Intensification Test (Optional/Extended)

III. Typical On-site Scenarios

• Full-load Parking on Ramp: The forklift is parked on a 15% steep slope with full load, and engineers check for sliding and sufficient braking force.

• Tiltable Platform Stability: The forklift drives onto the tiltable platform, which is gradually tilted, and engineers closely monitor whether the outer wheels leave the ground.

• Full-load Lifting and Lowering: The forks lift the standard counterweight, and the speed, abnormal noise and sliding amount are measured throughout the process to check if they exceed the standard.

• High-speed Emergency Braking: The forklift accelerates to the specified speed and brakes suddenly, leaving brake marks on the ground, and the instrument measures the braking distance.

• Noise Test: The forklift runs at idle speed and full load, and engineers collect data with a sound level meter at specified points.

• 
  

IV. On-site Conclusion and Follow-up

• Real-time Judgment: Inspection engineers record data item by item and judge qualified/unqualified against the standards.

• Unqualified Items: Pointed out on site immediately; the enterprise can conduct a re-test after rectification.

• Test Report: After all items are passed, a type test report is issued, and the enterprise uses this to apply for the Special Equipment Manufacturing License and Product Certificate of Conformity.

V. On-site Characteristics

• Strictness: All data must meet the standards strictly with no ambiguous space.

• Safety: Protective and emergency measures are in place throughout the process to prevent overturning and falling objects.

• Objectivity: Third-party inspection and traceable data ensure fairness and impartiality.
